Spring MVC send a String from the client to controller using DOJO

Question

I have the following Code on my Client

    var value = {"userId":form.userId.value};

var xhrArgs = {
    url : messageUrl,
    handleAs : "text",
    content: value,
    load : displayMessages,
    error : function(error) {
        dojo.byId("displayArea").innerHTML = "Error aquiring messages";
    }
};
dojo.xhrGet(xhrArgs);
}

And on my server side controller code

@RequestMapping(value = "/getMessages.htm", method = RequestMethod.GET)
public @ResponseBody String showMessageTable(@RequestParam("userId") String userId,ModelMap params)
{

I am getting a 400 error saying

The request sent by the client was syntactically incorrect ()

Could someone explain what i'm doing wrong? I have tested the dojo code with firebug and the value seems to be passing just fine. Thanks!

You may want to check your Accept header, it should be application/json — Biju Kunjummen

@BijuKunjummen Do I have to do that even if im moving text? Isn't that for json objects? — MangoCrysis

Oh, okay did not realize that, you have annotated the response with @ResponseBody, Spring will then try and convert the response to json or xml based on the accept header. Just remove the @ResponseBody and it should then try to resolve the view(say a jsp) based on what you are returning from the showMessageTable method. — Biju Kunjummen

@BijuKunjummen Thanks for the reply! The ResponseBody annotation was something I just added for testing purposes. It doesn't give me the JSP page even if I didn't have it. So my code on the client side looks good? I am still getting the status 400 error. Also to note. when I put the url, the exact one that dojo is sending back in the address bar it takes me to a new page and displays data. So I know the MVC is working. — MangoCrysis

Just to confirm, with DOJO when you send a request, is it a normal POST or GET with the userId field a normal request parameter and NOT a json. — Biju Kunjummen
